Application May 16, 1936, Serial No. 80,086 3 Claims. (Cl. 126-61) This invention relates to an improved stove and more particularly to a wood burning stove and one object of the invention is the p-rovision of a stove including upper and lower drums enclosed 5 in a casing or housing through which air .passes and is heated by the drums.

Another object of the invention is to so arrange the drums that one will be disposed over the other and smoke and other products of combustion pass through it from the lower drum in which wood is to be burnt, the drums being of such dimensions and the Vcasing so spaced from the drums that there will be ample space for air to pass upwardly through the casing about the l5 drums.

Another object of the invention is to provide improved means for supporting the drums, one above the other, and to also provide improved means for supporting the casing about the drums with its lower end spaced upwardly from the floor of a room so that air may easily enter the drum at its lower end. It is also an object of the inventionv to so mount the casing that while it can be easily set in place or removed when necessary it will be prevented from shifting longitudinally of the drums out of its proper position.

Another object of the invention is to provide a stove which can be manufactured at small cost and sold at a reasonable price.

The invention is illustrated in the accompanying drawing, wherein:

Figure 1 is a side elevation of the improved stove.

Figure 2 is a sectional view taken vertically through the stove.

Figure 3 is a fragmentary View looking at the front of the stove.

Figure 4 is a fragmentary sectional view taken along the line 4 4 of Figure 3 and illustrating the manner in which the casing is held against movement longitudinally of the drums when in place.

Figure 5 is a view in side elevation of a modified form of stove.

This improved stove consists briefly of upper and lower drums I and 2 which extend horizontally in vertical spaced relation to each other and are enclosed in a casing 3 open at its top and supported about the drums in spaced relation thereto and also in spaced relation to the oor of the room in which the stove is located. The lower drum constitutes a fire box and is provided with a fuel door l through which wood or other suitable fuel is passed into the drum and a lower draft door 5 having the usual slidable damper plate and adapted to be opened in order that ashes may be removed. The upper drum is offset longitudinally of the lower drum as shown in Figure 1 but may be located directly over the lower drum as shown in Figure 5 if so desired. While the drums may be specially constructed it is preferred to form them of old oil drums which can be cheaply obtained and thus reduce the cost of the stove. from the rear end of the lower drum with its upper end communicating with the rear end portion of thek upper drum and a smoke stack 'I rises from the front end of the upper drum. It will y thus be seen that smoke and other products of 15 combustion must pass vrearwardly through the lower drum, upwardly through the pipe 6 into the upper drum and then forwardly through the upper drum to rreach the smoke stack l. Thev two drums will therefore be heated to a high 20 temperature and air which passes upwardly about the drums will be quickly warmed.

The two drums and the casing are supported by legs or standards 8 formed of metal bars which are disposed vertically at opposite sides of the 25 drums and welded or otherwise firmly secured thereto as shown at 9. By this arrangement the legs will be firmly anchored to the drums and prevented from moving out of their proper positions. Arms or brackets I0 project laterally of the legs 30 from outer side faces thereof in spaced relation to their lower ends and terminate in upwardly projecting bills II so that when the casing 3 is set in place with its lower edge resting upon the brackets it will be prevented from shifting trans- 35 versely out of a position in which the drums will be disposed in the drum in centered relation thereto as shown in Figure 2. The casing is rectangular in top plan and of such length that its rear wall will be spaced rearwardly from the two 40 drums while its front wall will engage about the front end of the lower drum, a recess I2 being formed in the front wall to receive the drum as shown in Figure 3. U-shaped clips I3 of strong metal are welded to the lower drum and while 45 one has been shown at the top of the drum and the others at opposite sides thereof it will be understood that any number of clips desired may be provided. These clips are sor located that when the casing is lowered into place about the drums 50 marginal portions of the front wall about the recess I2 will engage in the clips and the clips serve to prevent the casing from shifting longitudinally out of its proper position.

When this improved stove is in use the drums 55 A smoke pipe 6 extends upwardly l0- are set in place in a room and supported above the oor by their legs 8. The casing is then applied and supported upon the brackets I where it will be held in spaced relation to the oor and the bills II and clips I3 prevent it from shifting transversely or longitudinally out of its proper position about the drums. 'Ihe smoke stack T is then connected with a chimney and a fire may be started in the lower drum which serves as a fire box. The wood is passed inwardly through the fuel door 4 and the slide of the draft door opened so that sufficient air will be admitted or the draft door may be opened to permit a draft to enter the re box. Air enters the casing through the open lower end thereof and passes upwardly through the casing about the drums and out through the open upper end of the drum as indicated by the arrowsI in Figures l and 2. As the air passes upwardly through the casing it is heated by the two drums and will be very warm when it passes out through the upper end of the drum. A very good circulation of air takes place through the casing and air in a room will be quickly heated and the room kept warm. When repairs are necessary the casing can be easily lifted out of place about the drum and the two drums will be exposed to View. If so desired the casing may be omitted as shown in Figure 5 in which case provision of the brackets I0 is not necessary.

Having thus described the invention, what is claimed is:

1. In a stove, upper and lower horizontally disposed drums, the lower drum constituting a fire box and projecting forwardly beyond the upper drum, a smoke pipe extending upwardly from the rear end of the lower drum and communicating with the rear end portion of the upper drum, a smoke stack rising from the front end of the upper drum, standards extending vertically at opposite sides of said drums and firmly anchored thereto with their lower portions projecting downwardly below the lower drum to support the drums in an elevated position, brackets projecting laterally from outer sides of lower portions of the standards below the lower drum and having upturned bills at their outer ends, a casing open at its top and bottom and disposed about the drums and having side walls and a rear wall spaced from the drums and a front wall formed with a recess receiving the front end portion of the lower drum, and U-shaped clips carried by the front end of the lower drum and projecting radically therefrom and straddling portions of the front wall of the casing about the recess to prevent shifting of the casing longitudinally of the drums, said casing resting upon said brackets and engaged by the upturned bills thereof to prevent shifting of the casing transversely of the drums.

2. In a stove, upper and lower drums, a smoke pipe establishing communication between the drums, a smoke stack rising from the upper drum, supporting legs anchored to said drums and projecting downwardly below the lower drum, brackets carried by said legs and projecting outwardly therefrom in spaced relation to lower ends thereof, a casing about said drums open at its top and bottom and resting upon said brackets, the brackets having upturned portions for engaging the casing and preventing transverse movement thereof, a recess being formed in the casing to receive the lower drum, and U-shaped clips carried by the lower drum and straddling portions of the casing about the recess to prevent shifting of the casing longitudinally of the drums.

3. In a stove, upper and lower horizontally extending drums, a smoke pipe establishing communication between the drums, legs anchored to the drums at opposite sides thereof and supporting the upper drum in Vertical spaced relation to the lower drum, said legs extending downwardly below the lower drum to support the same above a oor, brackets carried by said legs above lower ends thereof, a casing about said drums resting upon said brackets and having a recess snugly receiving the lower drum, and clips carried by the lower drum and engaging the casing about the recess to prevent shifting of the casing longitudinally of the drums.
